Tired of the constant dripping from an old faucet in your Vancouver bathroom? Want to give it a makeover without breaking the bank? Here’s the good news – replacing that sink faucet in your bathroom is incredibly easy, much more than you might think!

As someone who’s tackled this project myself, I can tell you firsthand that with the right tools and some know-how, you can swap out that old faucet for a shiny new one in no time. Let’s jump in and bring some magic to our bathroom space, shall we?

Gather the Necessary Tools and Materials

Before replacing your bathroom sink faucet, it’s crucial to gather all the necessary tools and materials. Trust me, there’s nothing worse than being elbow-deep in plumbing only to realize you’re missing a vital tool.

Safety Precautions

Safety should always come first. Make sure to wear safety glasses to protect your eyes from any debris or splashing water. Gloves are also a good idea to keep your hands clean and avoid any cuts or scrapes.

Preparing the Work Area

Lay down a towel or drop cloth in the sink cabinet to catch any water that may drip during the faucet replacement process. This will help protect the cabinet and make cleanup a breeze. You’ll need a few key tools for this job:

• Basin wrench
• Adjustable wrench
• Channel-lock pliers
• Putty knife
• Plumber’s putty
• Silicone caulk
• Mineral spirits or rubbing alcohol for cleaning

Having these tools on hand will make the process go much smoother. I can’t tell you how many times I’ve started a project only to have to run to the store midway through because I forgot something essential.

Turn Off the Water Supply

Before you start any plumbing project, turning off the water supply is a must. The last thing you want is a geyser in your bathroom.

Locating Water Shutoff Valves

Look for the hot and cold water shutoff valves underneath the sink, typically located in the cabinet. They’re usually oval-shaped compression valves connected to the water supply lines.

Turning Off Hot and Cold Water

Turn the hot and cold shutoff valves clockwise to turn off the water supply to the faucet. After shutting off the valves, turn on the faucet to release any remaining water pressure in the lines. Let it drain completely. I remember my first time replacing a faucet – I forgot this step and ended up with a face full of water when I disconnected the supply lines. Learn from my mistake.

Remove the Old Faucet

Now it’s time to say goodbye to that old, leaky faucet and make way for the new.

Disconnecting Water Supply Lines

Disconnect the flexible water supply lines from the shutoff valves using your adjustable wrench. Have a bucket ready to catch any residual water that may drip out.

Removing Faucet Mounting Nuts

Locate the mounting nuts that hold the faucet in place under the sink. Use your basin wrench to loosen and unscrew these nuts. If they’re stuck, apply some penetrating oil and let it sit for a few minutes before trying again.

Lifting Out the Old Faucet

With the mounting nuts removed, you should be able to lift the old faucet out from the top of the sink. If it’s being stubborn, gently wiggle it back and forth until it comes loose. Be careful not to damage the sink surface. Don’t forget to remove the old faucet’s lift rod and disconnect it from the sink’s drain assembly.

Clean the Sink Surface

Before installing your shiny new faucet, it’s important to start with a clean slate.

Removing Old Plumber’s Putty or Silicone

Use your putty knife or a flathead screwdriver to scrape away any old plumber’s putty or silicone caulk from around the faucet holes on top of the sink. This can be a bit tedious, but take your time and make sure to remove as much of the old sealant as possible.

Cleaning the Sink Surface

Once you’ve scraped away the old putty or caulk, clean the sink surface thoroughly with mineral spirits or rubbing alcohol. This will remove any residue, oils, or grime and help the new faucet form a tight seal. I once skipped this step in a rush and ended up with a slow leak around my new faucet base. Trust me, taking the time to properly clean and prep the surface is worth it in the long run.

Install the New Faucet

You’re in the home stretch now. It’s time to install that beautiful new bathroom faucet.

Placing the Faucet

Carefully place the new faucet into the holes on top of the sink, feeding the supply lines and mounting hardware through from above. If your faucet comes with a rubber or plastic gasket, place it between the faucet and the sink surface. Make sure the faucet is centered and facing the right direction before moving on.

Securing the Faucet

From under the sink, slide the mounting nuts onto the faucet’s mounting posts or threads. Hand-tighten these nuts, then give them an extra 1/4 turn with your basin wrench to fully secure the faucet in place. Be careful not to over-tighten, as this can damage the sink or faucet. Just make it snug.

Connecting Water Supply Lines

Attach your flexible water supply lines to the corresponding hot and cold faucet supply posts. Finger-tighten the coupling nuts, then use your adjustable wrench to give them an extra 1/4 turn. Again, don’t over-tighten. I always like to use a bit of plumber’s tape on the threads before attaching the supply lines for an extra layer of leak protection.

Reconnect Water Supply and Test

You’re almost done. Just a few final steps to go.

Turning On the Water Supply

Turn the hot and cold water shutoff valves counterclockwise to turn the water supply back on. Keep an eye out for any immediate leaks from the supply line connections.

Checking for Leaks

Turn on your new faucet and let the water run for a minute or two. Carefully inspect all the connections, including the water supply lines and the base of the faucet, to make sure there are no leaks. If you spot a leak, turn the water off and double-check that all connections are tight and secure.

Testing Faucet Functionality

While the water is running, test out your new faucet’s functions. Make sure both hot and cold water are flowing properly and that there’s adequate water pressure. Also, check that the faucet handles turn smoothly and that the water shuts off completely when the faucet is closed.

Install the Drain Assembly

If your new faucet comes with a matching drain assembly, now’s the time to install it.

Applying Plumber’s Putty

Roll a small snake of plumber’s putty between your hands and apply it around the underside of the new drain flange. This will help create a water-tight seal.

Inserting the Drain Assembly

Insert the new drain body up through the drain hole, with the flange sitting on top of the putty. From under the sink, slide on the rubber gasket and friction washer before threading on the mounting nut.

Tightening the Drain

Hand-tighten the mounting nut, then use your channel lock pliers to give it an extra 1/4 turn to fully secure the drain. Don’t over-tighten, as this can crack the sink or damage the drain. Reconnect the sink’s P-trap to the new drain’s tailpiece, and you’re set.

Clean Up and Finish

Congratulations, you’ve successfully installed your new bathroom sink faucet.

Cleaning the Work Area

Wipe away any excess plumber’s putty that may have squeezed out from under the drain flange. Clean the sink, faucet, and surrounding area with a soft cloth to remove any water spots or fingerprints. Don’t forget to wipe out the sink cabinet and remove the towel or drop the cloth you used to catch any water.

Disposing of Old Faucets and Materials

Properly dispose of your old faucet, drain, and any used materials like the old supply lines or mounting hardware. Some local scrap yards may even pay you for the metal.

Enjoying Your New Bathroom Sink Faucet
